Frequently Asked Questions

What correlated colour temperature range does Opaline Inground TW cover?

It smoothly transitions across a wide spectrum from 1800K (ultra-warm candlelit) to 5700K (crisp cool daylight).

How is the dual-channel Tunable White controlled?

Controlled via 2-channel 24V PWM drivers utilizing DALI-2 DT8 Tunable White, 0-10V dual-dimming, or wireless Casambi Bluetooth profiles.

Is the light output completely uniform?

Yes, the solid continuous opal encapsulation provides 100% dot-free, glare-free light emission across the full length.
